Definitions

  • the invention relates to an implement for treating a soil surface, such as for example raking together grass and/or hay, said implement being provided with a frame comprising at least one, preferably motor-drivable, treating unit provided with treating elements for treating the soil surface.
  • the implement is provided with measuring means which are suitable for feeling and/or scanning the soil surface to be treated and for determining ground irregularities, such as slopes and/or holes for example, that may be present in the soil surface, as well as with adjusting means that adjust automatically the orientation and/or height of the treating unit relative to the soil surface, on the basis of the measuring results of the measuring means.
  • the treating unit is designed as a rake for example, it is thus possible to realize good raking results, even in case of an uneven soil surface, due to the fact that the entire treating unit is optimally positioned.
  • this agricultural machine has similar advantages.
  • the implement may be provided, according to a further embodiment of the invention, with a storage medium which is suitable for storing data regarding the soil surface, in particular the irregularities in the soil surface to be treated, as well as with means for determining the position, such as DGPS for example, with the aid of which the current position of the treating unit is determined, and with adjusting means that adjust automatically the orientation and/or height of the treating unit relative to the soil surface, on the basis of the current position of the treating unit and the stored data regarding the soil surface at that place.
  • a storage medium which is suitable for storing data regarding the soil surface, in particular the irregularities in the soil surface to be treated, as well as with means for determining the position, such as DGPS for example, with the aid of which the current position of the treating unit is determined, and with adjusting means that adjust automatically the orientation and/or height of the treating unit relative to the soil surface, on the basis of the current position of the treating unit and the stored data regarding the soil surface at that place.
  • the invention also relates to an implement for treating a soil surface, such as raking together grass and/or hay for example, said implement being provided with a frame comprising at least one, preferably motor-drivable, treating unit provided with treating elements for treating a soil surface, characterized in that the implement is provided with a storage medium which is suitable for storing data regarding the soil surface, in particular the irregularities in the soil surface to be treated, as well as with means for determining the position, such as DGPS for example, with the aid of which the current position of the treating unit is determined, and with adjusting means that adjust automatically the orientation and/or height of the treating unit relative to the soil surface, on the basis of the current position of the treating unit and the stored data regarding the soil surface at that place.
  • a storage medium which is suitable for storing data regarding the soil surface, in particular the irregularities in the soil surface to be treated, as well as with means for determining the position, such as DGPS for example, with the aid of which the current position of the treating unit is determined, and with adjusting means
  • the treating unit is adjusted on the basis of measurements carried out with the aid of the measuring means and on the basis of the data regarding the soil surface stored in the storage medium. It is further possible, if desired, to adjust data regarding the soil surface stored in the storage medium with the aid of data regarding the soil surface at that place obtained by the measuring means.
  • the measuring means comprise one or more sensors which, seen in the direction of travel of the implement, feel and/or scan the soil surface in front of the treating unit.
  • the sensors are disposed on the frame.
  • the sensors are designed as ultrasonic sensors.
  • the sensors may comprise a camera.
  • the adjusting means comprise control elements which are suitable for tilting the treating unit to the front respectively to the rear and/or laterally, seen in the direction of travel of the implement.
  • the adjusting means comprise at least one control element and preferably three control elements.
  • the treating unit is capable of being tilted about one or more axes and thus being adjusted. According to another inventive feature it is further possible to adjust the treating unit in height relative to the soil surface. In the situation that three control elements are applied, it is possible to adjust the treating unit omnidirectionally relative to the soil surface.
  • the control elements are designed as control cylinders or stepper motors.
  • the adjusting means comprise one or more ball joints.
  • the adjusting means comprise a clinometer which is suitable for determining the angle that is enclosed by the treating unit and the soil surface.
  • the adjusting means comprise height measuring means which are suitable for determining the height assumed by the treating unit relative to the soil surface.
  • the treating unit is designed as a motor-drivable rake.
  • the rake comprises tine arms which are pivoted through a curve path.
  • the implement comprises a driving speed sensor.
  • the implement comprises an rpm-sensor which is suitable for determining the number of revolutions of the treating unit and/or the treating element. With the aid of the driving speed sensor and the rpm-sensor it is possible, depending on the conditions of the surface to be treated, optimally to adjust the working depth of the treating unit and/or the treating element. With a rake or a tedder for example, at an unchanging number of revolutions of the treating unit and at an increased driving speed, it is possible to choose a deeper adjustment of the treating unit and/or the treating element.
  • Figure 1 is a side view of a first embodiment of an implement 1 according to the invention, said implement being provided with a frame 2 comprising a treating unit 3 which is designed as a rake in the present embodiment.
  • the rake 3 is motor-drivable via a transmission 4.
  • the frame 2 is further provided with coupling means 5 with the aid of which the implement can be coupled to a vehicle, such as a tractor for example.
  • the rake 3 is supported by a wheel set 6 that is designed as a tandem wheel set.
  • the rake 3 is further provided with tine arms 7 having at their ends rake tines 8.
  • the tine arms 7 are controlled via a central box 9 with a curve path therein.
  • the central box 9 is connected with the frame 2 via a horizontal hinge pin 10.
  • the adjusting means 11 comprise a control cylinder 12 which is preferably designed as a servo-pneumatic control cylinder.
  • the implement 1 is further provided with measuring means 13 which are suitable for feeling and/or scanning the soil surface to be treated and determining ground irregularities, such as slopes and/or holes for example, that may be present therein.
  • the measuring means 13 comprise a plurality of sensors 14 which are disposed near the front side of the frame 2 and which are capable of feeling and/or scanning the soil at least over the full working width of the implement 1.
  • the rake tines 8 of the rake 3 are adjusted with the aid of the adjusting means 11 in such a manner that the distance from the rake tines to the soil is maintained. In this way the rake tines are prevented from moving through the soil or extending far above the soil, so that they cannot take along grass or hay.
  • FIGS 2 and 3 show a second embodiment of an implement according to the invention, in which parts corresponding to those in the first embodiment are indicated by the same reference numerals.
  • the frame 2 is supported by a wheel set 6.
  • the wheel set 6 is disposed after the treating unit 3.
  • the treating unit 3 is fitted to the frame 2 so as to be hingeable on a ball joint 16.
  • Two control cylinders 12 are further provided between the central box 9 and the frame 2.
  • the control cylinders 12 are also hingeably connected with the frame 2 by means of a ball joint 16.
  • the measuring means 13 comprise three sensors 14 with the aid of which ground irregularities, such as slopes and/or holes for example, can be determined. Due to the fact that the treating unit 3 is adjustable in height by means of the two control cylinders 12, the treating unit 3, seen in the direction of travel of the implement 1, can be tilted not only to the front and/or to the rear, but also laterally. In this manner it is possible to adjust even better the orientation and/or height of the rake tines 8 in relation to slopes (and/or holes) in the soil.
  • FIGS 4 and 5 show a third embodiment of the implement according to the invention, in which parts corresponding to those in the first and second embodiment are indicated by the same reference numerals.
  • the point in which the third embodiment differs most from the second embodiment is that the third suspension point of the treating unit 3 is not constituted by a beam 15, but by a control cylinder 12 which is connected with one end to the frame 2 by means of a horizontal hinge pin and which is connected with its other end to the transmission 4 by means of a horizontal hinge pin 18.
  • the treating unit 3 is connected with the frame 2 by means of three control cylinders 12 it is possible optimally to position the rake tines 8 of the treating unit 3 omnidirectionally relative to the frame 2, so that there can be achieved an excellent adjustment of the rake tines 8 to the soil in relation to slopes and/or holes therein.
